LIGHT EMITTING DIODE AND METHOD OF FABRICATING THE SAME

摘要

A disclosed light emitting diode comprises: a substrate; a semiconductor layer formed on one surface of the substrate; an anti-reflective element formed on the other surface of the substrate. The anti-reflective element includes a nanopattern. The present invention can ameliorate light extraction efficiency by reducing total reflection of light traveling toward air through the substrate from a semiconductor stacking unit as the anti-reflective element is disposed between the substrate and the air. Furthermore, each anti-reflective element can be formed in a Moth-eye pattern as formed in the nanopattern. Accordingly, the reflection generated at the interface between the substrate and the semiconductor layer.
